WHEEL ATTACHMENT FOR SLEIGH-RUNNERS.

Application filed October 1, 1915, Serial No. 53,571.

To all whom it may concern Be it known, that I, Jacon Lnwrs Bivrxnn, a citizen of the Dominion of Canada residing at the ity of Winnipeg, in the Province of lilanitoba and Dominion of Canada have invented certain new and useful Improvements in \Vhecl i rttachments for Sleigh Runners. of which the following is a specification.

My invention relates to improvements in attachments for the runners of sleighs more nu'ticularly boh-sleighs used for carrying heavy loads and comprises individual wheels for each runner which are normally out of contact with the ground, but which may be lowered to partially support the run ner when bare ground is encountered.

The object of the invention is to provide an attachment for the purpose stated which may be applied to sleighs of standard construction without involving structural changes in the sleigh itself, and which will be strong and durable and comparatirely simple of application and inexpensive in first cost. I attain these objects by the means set out in the following specification and fully illustrated in the accompanying drawings, in which Figure 1 is an elevation of the inner side of a sleigh-runner showing my improvement attached thereto.

Fig. 2 is an elevation of the opposite side of the runner.

Fig. 3 is a front view of a sleigh with my attachments on each of the runners.

Fig. 4 is a front view of the attachment complete and apart from the sleigh.

Fig. 5 is the plate which secures to the sleigh-runner and carries the wheel.

Fig. 6 is a side view of the wheel and the block on which it is mounted.

Fig. 7 is an edge view of the same showing the guide members on the side of the block.

Fig. 8 is a side view of the pin block used to maintain the wheels at the desired points on the attachment plate.

Fig. 9 is a rear view of the same.

Fig. 10 is a detail showing the bolt which secures the wheel block to the attachment plate, with the pin block thereon and the locking pin in position in the bolt.

Similar characters of reference indicate similar parts throughout the difierent views.

Specification of Letters Patent.

Renewed March 6, 1917. Serial No. 152,878.

by the bench The attachment, indicated as B, comprises a plate C, turned at the top to form a hook 4. adapted to engage the top of the brace rod 6, running forwardly from the bench 3, to the runner.

The plate C is preferably shaped to follow the outline of the brace (i. and it is provided with openings 7 and 8 for passage of the bolts 9 by means of which it is secured to the runner 1 and bunk 2 respectively. T he plate C may be of any material but it is preferably of iron of a. gage insuring stability. In the plate C a. slot 10 preferably convergingly placed with respect to the bunk and at either sides of the slot are shown pairs of perforations indicated as and 13. i A wheel is rota .ably mounted. prefer ably in sheave style in a block 15, having projections 16 and 17 on the side thereof adapted for the longitudinal movement in the slot 10 in the plate C, the relative position of the block to the plate C being thereby maintained. i

A. bolt 18 is secured in the block 15, thence passing through the slot 10 in the plate C. and the openin 19 in the block 20, the latter being provided with projecting pins 21 adapted to enter either the perforations 12 or 13 in the plate C. The bolt 18 is provided with an opening through which a pin may be removably passed to hold the different parts in engagement, and it is also preferably provided with a flat head As previously mentionech the wheels are normally out of contact with the ground, they being maintained in raised position by the pins 21 on the blocks 19 disposed in the perforations 12 in the plate C. lVhen it becomes desirable to make use of the wheels. the sleigh is raised preferably by means of a jack-screw 24: (Fig. 3) although when this is not handy a lever or other mechanical lifting means may be used. The pins 22 are next withdrawn from the openings in the bolts 18 allowing of the sliding of the blocks to remove the pins 21 from the perforations 12 in the plate C. The bloclrs 15 may be then lowered till the pins 21 reach and enter the perforations 13, when the pins 21 are again replaced in the openings in bolts 23. thus serving to hold the blocks 15, and 20. in engagement with the opposite side of the plate C in their lowered position the projections 16 and 17 on the sides of the blocks 15, being disposed. in the slots 10 in the plates C and serving to prevent rotation of the blocks 15, upon or with bolts 18.

From the foregoing description it will be understood that it is not the intention of the invention that the runners should be fully supported by the Wheels, but that these are; only an auxiliary device to be used when necessary, and that when they are used a portion of each runner will still be in contact with the ground.

Having thus fully described my said invention what I claim as mine and desire to secure by Letters Patent is 1. An attachment for a sleigh comprising a wheel, means to support the wheel and means to support the wheel supporting means from the runner of the sleigh, said last named means comprising a member having an elongated slot, said wheel supporting member having guide members longitudinally movable in said slot, a bolt passing therethrough and a clamp member slidably mounted on said bolt to hold said clamp and wheel supporting members in intimate engagement with the opposite sides of said slotted member.

2. An attachment for a sleigh comprising a plate having a hook to engage the benchbrace and means to secure it to the runner of the sleigh, an elongated slot in the plate, perforations contiguous to the slot; a wheel, a block in which the wheel is journaled and projections on the block longitudinally movable ,in said slot, aclamp member slidably mounted on the bolt and having pins adapted to enter the openings in the plate, and releasable means on the bolt to secure the clamp and block in intimate engagement with the opposite sides of the plate or disengageable to allow their being moved up or down thereon to change the position of the wheel.

In testimony whereof, I atlix my signature in the presence of two witnesses.
